Description

Horizontal boiler for heating water

Technical field

The present invention relates to a kind of hot-water boiler, especially relate to a kind of civilian Horizontal boiler for heating water.

Background technology

Vertical vertical fire tube structure hot-water boiler is by the combustion chamber, lower perforated plate, pyrotechnics tube bank, upper perforated plate, the compositions such as upper smoke-box.Combustion chamber and heat-absorbing structure belong to up and down conjoined structure, its advantage is that floor space is little, compact conformation, but not enough place is also arranged: 1 enters the pyrotechnics tube bank because the high-temperature flue gas that produces during the fuel combustion on the fire grate directly washes away lower perforated plate, and localized hyperthermia and thermal expansion stress are inevitable; Distance from the fire grate to the lower perforated plate is relatively shorter, when Coal-fired capacity increases, when combustion intensity strengthens, burns insufficient almost inevitable; 2 in clear smoke-fire-tube of boiler operatiopn stage during carbon deposit, can occur that carbon deposit drops on the coal seam and is lighted and the phenomenon of smoldering then occurs; If 3 vertical vertical fire tube hot-water boilers combustion intensity at the beginning of each run is not enough strong, if and this moment, water temperature was lower, can generate more condensed water in the endothermic tube, condensed water can drop on the fuel bed again easily, and then has influence on the fired state of fuel in combustion chamber.

Summary of the invention

In order to overcome the technical deficiency of conventional hot water boiler, the invention provides a kind of vertical fire tube hot-water boiler, the technical problem that this boiler will solve is: allow lower perforated plate following no longer be the combustion chamber but independently play smoke-box, allow lower perforated plate no longer be in hot environment, with regard to not occurring that carbon deposit drops on the fuel bed and the phenomenon of smoldering, can not occur in addition that condensed water drops on the fuel bed and the phenomenon of impact burning during so clear carbon deposit yet; Aspect clear carbon deposit, guarantee that the brush for smoke pipe handle is vertical with smoke-fire-tube, just can more be conducive to remove the carbon deposit in the smoke-fire-tube; Increase running time and the range ability of high-temperature flue gas before entering the smoke-fire-tube heat dump, can realize the abundant burning of fuel; Using the multiple-pass heat-absorbing structure can be in the situation that compact conformation effectively reduces exhaust gas temperature.The horizontal type structure of arranging about combustion chamber and heat dump adopt, relatively independent, increase running time and the range ability of high-temperature flue gas before entering the smoke-fire-tube heat dump, realized the abundant burning of fuel, also strengthened the endothermic effect of heat dump heat-absorbing structure before; The smoke-fire-tube of heat dump part vertically interts in upper lower perforated plate, the top of upper perforated plate is upper smoke-box, no longer include the combustion chamber below the lower perforated plate but the relatively low lower smoke-box of temperature, can guarantee that the condensed water in the smoke-fire-tube at the beginning of the boiler operatiopn can not affect the combustion position of combustion chamber, the carbon deposit that falls in the time of yet can guaranteeing clear carbon deposit can not lighted and be smoldered; Upper smoke-box selects water-cooling structure, and lower smoke-box selects non-water-cooling structure, and the area of lower perforated plate is wanted obvious area greater than upper perforated plate like this, and the smoke-fire-tube that is in lower perforated plate can be far away apart from the edge of tube sheet, is conducive to alleviate the stress that thermal expansion produces; Setting up of vertical clapboard determines running route and the stroke of high-temperature flue gas in smoke-fire-tube in the smoke-box up and down, and the multiple-pass structure can effectively reduce exhaust gas temperature, also allows boiler structure compacter.

The technical solution adopted for the present invention to solve the technical problems is:

Combustion chamber and heat dump are relatively independent, about arrange the expansion chamber that above the combustion chamber, is furnished with buffer board and is formed by buffer board.The buffer board of top, combustion chamber, expansion chamber, and the upper smoke-box of smoke-fire-tube heat dump upper perforated plate top is together as the running route of high-temperature flue gas before entering the pyrotechnics tube bank, running time and the range ability of high-temperature flue gas have been increased, realize the abundant burning of fuel, also strengthened the before endothermic effect of heat-absorbing structure of heat dump.

The structure of arranging about combustion chamber and heat dump adopt, during clear carbon deposit, carbon deposit drops on lower smoke-box, because the temperature of lower smoke-box is relatively low, the temperature of lower smoke-box bottom more under burning-point, the phenomenon of smoldering so the carbon deposit burning can not occur in the time of can guaranteeing carbon deposit in the clear smoke-fire-tube; Because it is not the combustion chamber that pyrotechnics is restrained the following of lower perforated plate, can not affect the combustion position of combustion chamber so can guarantee the condensed water at the beginning of the boiler operatiopn yet.

Upper smoke-box selects water-cooling structure, and lower smoke-box selects non-water-cooling structure, and the area of lower perforated plate is wanted obvious area greater than upper perforated plate like this, and the smoke-fire-tube that is in lower perforated plate can be far away apart from the edge of tube sheet, is conducive to alleviate the stress that thermal expansion produces.

The setting up and have or not and determine running route and the stroke of high-temperature flue gas in smoke-fire-tube of vertical clapboard in the smoke-box up and down, the multiple-pass structure can effectively reduce exhaust gas temperature, also allows boiler structure compacter; Miniature boiler can use two row layer heat-absorbing structure, when the power of boiler is larger, for fear of the too high quantity that can increase as required vertical clapboard in the smoke-box up and down of exhaust gas temperature, makes it to become the multiple-pass structure.

Outlet flue is located at the side of smoke-box on the second stroke, there is clearly carbon deposit hand hole door the top of upper smoke-box, can opening clearly, the carbon deposit hand hole door carries out the cleaning of carbon deposit, the size requirements of clear carbon deposit hand hole door realizes the smoke-fire-tube all standing to the area under one's jurisdiction, also can adopt built-in type brush for smoke pipe structure in the situation that do not open the clearly clear carbon deposit of carbon deposit hand hole door, so clear carbon deposit is convenient.

Operation principle of the present invention is: on two stroke boilers, the high-temperature flue gas that produces during fuel combustion on the fire grate is operation upwards, washing away combustion chamber wall and combustion chamber binds, export the upper smoke-box that enters the first stroke smoke-fire-tube bundle through buffer board structure and high-temperature flue gas afterwards, under the draft of chimney, enter the first stroke smoke-fire-tube bundle downwards, enter afterwards smoke-box on the tube bank of public lower smoke-box, the second stroke pyrotechnics, the second stroke, at last by the side go out tobacco pipe and chimney is discharged to outdoor.

The invention has the beneficial effects as follows: combustion chamber and heat dump be relatively independent, about layout, comparatively ideal bags height, cushioning fender and expansion chamber also have the abundant burning that exists for of upper smoke-box to create condition; And the pyrotechnics tube bank adopts two row layer structure in the situation that compact conformation effectively reduces exhaust gas temperature, to improve the thermal efficiency; Clearly carbon deposit hand hole door is arranged above the upper smoke-box, and clear carbon deposit is convenient, and because lower smoke-box also is relatively independent, does not drop on phenomenon on the fuel bed so can not occur carbon deposit during clear carbon deposit; Also have lower smoke-box temperature relatively low, for setting up of built-in type brush for smoke pipe provides possibility; Because independently combustion chamber heat absorption, effectively increased the before endotherm area of heat-absorbing structure of smoke-fire-tube heat dump, alleviated the burden of pyrotechnics tube bank in the heat dump, the phenomenon that lower perforated plate in the vertical structure boiler bears localized hyperthermia can not appear, not only reduce stress but also reduced the generation of incrustation scale, improved service life.Advantage of the present invention is rational in infrastructure in sum, and the thermal efficiency is high, and is easy to use, long service life.
